dream fragment

I'm at home, but something strange is happening. My backyard looks different and takes you to another place, something was wrong with the alarm, and people were coming and going.

This dream was like a videogame, i entered a castle in order to fight a witch.
Then i showed my sister another videogame, but she didn't like it.

I could not remember any more because when i woke up i noticed i was late for college and that made me nervous
